2.将二进制文件：docker-20.10.19.tgz 拖入服务器目录/home/admin/解压
tar -zxvf docker-20.10.19.tgz
3.将docker文件移动到可执行文件目录下
mv /home/admin/docker/* /usr/bin
4新建配置docker.service文件
vim /etc/systemd/system/docker.service
5…添加docker相关配置文本
#文本内容开始
[Unit]
Description=Docker Application Container Engine

After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
